Notes
At the Peachtree Ridge HS track doing HRBT-110 easy for 8 miles. Wore jacket, neck warmer, hat and gloves. One of the other usual guys who is really fast got there same time as I did and left when I had 1.25 miles left.
Average 12:45.4, cadence 159.4 for the HR of 110. Bad static electricity spikes. Dew point was only 1.1. I think this caused some of the bad numbers. First mile I would have still been a bit damp from perspiration from the car, but afterwards the spikes got really bad every time I tried to speed up a bit.
